DUMP'ING HAY-RAKE.

SPEGIFICATION forming part of Letters Patent N0. 761,211, datedMay 31, 1904.

Application filed April 30, 1903.

T0 alt whom it may concern:

Be it known that 1, JOHN R. DANNER, a citizen of the United States, residing at 'Marsl field, in the county of Wood and State of VVisconsin, have invented a new and useful DumpingHay-Rake, of whichthe following is a specification. i

This invention relates generally to hayrakes, and more particularly to one adapted to dump the load by elevating the rake and stripping the load therefrom; and the object of the invention is to provide an improved mechanism for raising the rake, said mechanism being operated by means of a foot-lever, thereby leaving the driver the free use of both hands at all times. I

Another object of my invention is to provide a device in which the rake can be automatically held after being elevated or after the load has been discharged; and a still further object is to provide a device in which the rake can be dropped automatically after being elevated or after the load has been discharged and to provide means for taking up the jar incidenta to the dropping of the rake. With these objects in view the invention consists in the novel features of construction, combination, and arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this specification, Figure is a top plan View showing one end of the rake constructed in accordance with my invention. line 2 2 of Fig. 1 looking in the direction of the arrow. Fig. 3 is a detail perspective'view of the casting-plate. Fig. 4 is a detail perspective View of the pawl and members connected thereto. Fig. 5 is aview showing the curved band adapted to protect the ratchetwheel arranged upon the axle of the machine. Fig. 6 is a detail perspective view of the T- bolt employed for connecting the pawl to the casting-plate. Fig. 7 is a view illustrating the spring and nut which are connected to the shank of the T-bolt for the purpose of exerting a tension upon the pawl. Fig. 8 is a detail perspective View of the tripping-iron. Fig. 9 isa view illustrating one of the footlevers. Figs. 10, 11, and 12 are details of the 'vations of the pivot-bolt.

mechanism for returning the foot-lever to its normal position; Fig. 13 is a detail sectional view showing the manner of pivoting the said foot-lever. Fig. 14 is a view showing two ele- Fig. 15 is a detail pitman. Fig. 16 is a sectional view on the line 16 16 of Fig. 15. Fig. 17 is a sectional view similar to Fig. 2, showing the position of the parts when the rake-teeth are elevated Fig. 18 is a perspective view, parts being broken away and shown in section, illustrating the manner of securing the rake-teeth to the beam and showing the tooth-guard.

In carrying out my invention I employ a frame A, comprising the beams A and A connected at their ends by the timbers A and supported upon ground-wheels B', the frame and axle being connected by means of suitable rods D, and pivotally connected to the axle so as to revolve upon the same is the beam E,-

having the rake-teeth E connected thereto,

said beam and rake-teeth beingof the usual or any approved construction; I A serles of stripping-fingers E are connected to the beam A of the frameA and exv 7 tend rearwardly below the axle between and beyond the rake-teeth E, so that when the said rake-teeth are elevated the fingers IE will,

stripthe load thereform, thereby causing the load to be dumped at the point where thera'ke-teeth are elevated.

In order to elevate the rake so as to'dump same, I employ a ratchet-wheel F, which is rigidly mounted upon the axle U adjacent to the center of the same, and this ratchet-wheel is adapted to be engaged by a pawl G, pivotally arranged upon the casting-plate H and operated by means of a chain 1 and foot-lever ing seated in an angled cut-out portion H and secured to a laterally-projecting ear H This casting-plate is formed with a tubular bearing H through which the axle Gpasses and is also provided with a recessed and bifurcated boss H, in which the lower and bifurcated end G of the pawl G is seated, said pawl being secured in said boss by means of a T-shaped bolt G the head of which passes through the bifurcated portion of the pawl and extends downwardly through the bifurcated boss H and has a nut G upon its lower end, and surrounding the bolt and bearing upon the nut and the lower face of the boss H is a coilspring G the purpose of which it to exert a constant tension upon the pawl and keep it firmly seated in the boss H". The pawl G has an upwardly-extending arm (ii-carrying a hook G6, and in practice I prefer to construct this aim and pawl from a single piece of metalwhich is bent upon itself, as shown, and shaped into the suitable bearing which is bifurcated at G, as previously described.

The chain 1 is connected to the hook G, and, as previously stated, the pawl is operated by pressing upon the foot-lever K, causing the nose of the pawl to be thrown into engagement with the ratchet-wheel F. The pawl is also provided with a rearwardly-extending footpiece G against which a coil-spring G bears,

the opposite end of said spring bearing against a flange H, formed upon the casting-plate H. A lug G is formed on the foot G, the lower end of the spring G encircling the ing and being heldinplace by it. The purpose of this spring .is to aid in holding the pawl in its normal or inoperative position. Bolted to and sup-- ported by-the flange H' vis a tooth-guard E having a plurality of vertical'slots E equal in number to the number of teeth, and through these slots the teeth E work. This guard aids in supporting the teeth and protects them from severe strains.

A stop-post H projects from. the face of.

the casting-plate H and serves to limit the rearward movement of the arm Gr of the pawl Gr, thereby-holding the pawl in close proximity to the ratchet-wheel, so that a very slight movement of the foot-leverwill be sufficient to throw the nose of the pawl into engagement with the ratchet-wheel. When the pawl is thrown into engagement with the ratchet-wheel, the continued movement of said ratchet-wheel will raise the casting-plate, carrying itaround the axle and with it the beam E, causing the rake-teeth to be elevated, so as to dump the material accumulated by the said rake-teeth, and in order to disengage the rake after it has been elevated to the desired extent I employ a tripping-iron L, which is mounted upon the beam A of the frame A and projects upwardly and slightly rear- 1 wardly, so that it will clear the beam E and p engage the upper portion of the arm G thereby throwing the pawl out of engagement with the ratchet-wheel, and the moment the said pawl is disengaged the rake will drop back to its normal position and all of the parts will be returned to the positions shown in Fig. 2. The foot-lever K comprises two members K and K the member K carrying a pedal K upon which the foot of the operator is placed, while the member K terminates in a hook K, to which the forward end of the chain I is attached. The lever is formed with atubular bearing K which is surrounded by an annular flange K, producing a chamber within which a coil-spring K is arranged, one end of the said spring being fastened to the flange K, while the opposite end is fastened to a cap-piece K the pivot-bolt K upon which the lever turns, being held fast in a bracket K and the cap-piece K is rigid with the bolt, inasmuch as the ends of said bolt are square, as most clearly shown in Fig. 14. By means of this construction the lever will be held in its rearmost position, as indicated in Fig. 2, and the spring K will serve to return the said lever to such position the moment tension is relieved therefrom. The treadle M is arranged upon the forward member of the elbow-lever M, the rear member having a sleeve M connected therewith and in which moves a rod N, having a head N at the forward end, and surrounding said rod within the sleeve is a spring N the normal tendency of which is to hold the rod N in a forwardly projected position, said rod N being pivotally connected to a link 0, which is pivotally connected at its rear end to the upper end of the casting-plate H, as shown at O in Fig. 2. The rod N is formed with'a series of perforations through which thepivot-bolt connecting the link and rod is adapted to be passed, and by having a plurality of perforations the rake can be adjusted to any desired height, it being understood that the position of the casting-plate, and consequently the position of the rake, is regulated by the length of the link N and rod 0, the spring N holding all of the said parts under the proper tension, and when the lifting mechanism is disengaged and the rake dropped-this spring will take up the jar and hold the rake in its proper position.

A band P is'connected at its upper end to the beam E and encircles the ratchet-wheel F, the lower end of said band being connected to the perforated ear H projecting through the casting-plate H. This band serves to protect the ratchet-wheel and prevent grass or weeds becoming entangled therewith. By pressing upon the treadle M the rake will be firmly held to the ground while accumulating its load.

- When it is desired to dump the rake, it is only necessary to press sufficiently upon the pedal K to bring the pawl into engagement with the ratchet-wheel, and the continued for- [ward movement of the machine will cause the rake to be elevated completely, bringing the tripping-iron into operation, which will disengage the pawl from the ratchet-wheel, causing the rake-teeth to automatically fall back into operative position and to be held there by the rod N, link 0, and spring N but by continuing the pressure upon the pedal K on and after the elevation of the teeth and disengagement of the pawl from the ratchet-wheel the pawl will be drawn forward out of the seat H and held out of the said seat. When said pressure is removed, the pawl is again drawn back into its seat by the spring G3, and spring G will force it into operative position.

It may be stated that when the pawl is drawn out of the seat H it is effectively prevented from catching into the ratchet-wheel. After the rake is dumped the rake-teeth can be held up or dropped at any desired place at the will of the operator. 7
